 | | The plow is depicted on Egyptian monuments, mentioned in the Old Testament, and described by Hesiod and Vergil. |
 | | The early plow consisted simply of a wooden wedge, tipped with iron and fastened to a single handle, and a beam, which was pulled by men or oxen. |
 | | Standardized by 1870, the modern moldboard plow has been improved by various attachments, e.g., the colter, a sharp blade or disk that cuts the ground in advance of the share. |
